要約(英語): In order to obtain MMIC of a feed circuit called a HTBM (Hybrid Three Direction Beam Matrix) for making compact phased array antennas, the HTBM that uses LC circuitry as substitute for its transmission line was designed, experimentally fabricated and then evaluated at 1 MHz. In addition, a switch circuit for switching a beam direction was made using FETs and built into the HTBM. Antenna output was evaluated. Its results showed that the output gave close agreement with its simulation value and that the antenna-to-antenna phase difference and the level difference were less more than 7 degrees and 3.3 dB, respectively, in comparison with its ideal value.
